Found a planetary system where the central star and the planets rotate in different directions


Typically, in planetary systems, planets revolve around a star in the same direction as the star itself. An example is our solar system – the parent star rotates in the same direction with the orbits of the planets. However, it has now become clear that this rule does not always work.

Scientists Maria Hjorth and Simon Albrecht from Aarhus University in Denmark have shared their observations of the star system K2-290, which has a total of three stars with two planets orbiting the main star. – K2-290A. It turned out that this star rotates with an inclination of 124 degrees relative to the ecliptic in the direction opposite to the planets. Scientists published their research yesterday in the journal “Proceedings of the National Academy of Sciences”, in which they note that the cause of such an anomaly may be the gravitational effect of two other nearby stars. Surprising is the fact that both planets revolve around the star in the same direction.

This discovery is unique in stellar kinematics, the science that studies the formation of the motion of stars. It should be noted that in K2-290 is a so-called double star. In the artist’s view, such space objects may look something like the image above.
